I have a Brig 450 falcon with a 40HP 4 stroke Yamaha. Last fall on the way back from UT’s last home game we spent the night at anchor in a cove. The Admiral took the dink and dog to shore and hit hard oh some large rocks just below the surface damaging the prop. The boat has always been hard to get on plane with 4 to 6 adults and slow wit a max speed of 27 mph at WOT. I took the damaged prop to our local prop shop and he said that it was a large prop for a RIB.(13 inch pitch). After answering a few questions he keyed in on that I was 1,200 rpms low at WTO. He recommended a Michigan 4 blade 12 inch prop. I put it on today and tested it It jumped on plane faster, gained 1,000 RPM’s and ran 32.4 mph at WTO.
